Specification of Letters Patent.

Patented Mar. 2, 1915.

Application filed October 28, 1914 Serial No. 869,009.

To all whom it may concern 7 Be it known that 1, HERMAN J. BREN- ivncirn, a citizen of the United States, residing in Chicago, in the county of Cook and State of Illinois, have invented certam new and useful Improvements in Goggle- Lens Connections, of which the following is a specification.

My invention relates to goggles and the like and has particular reference to flexible connections for the lenses which serve the same purposeas hinged lenses without the disadvantages of hinges. v

The object of the invention is to provide improvements which lend -grea-t flexibility to the lense' connections and at the same time hold the lenses in their normal relation with substantial rigidity, or with such firmness as is desirable to hold the lenses in their proper relations to. the eyes of the .user.

Another object 'is to provlde a neat and' attractive construction, and a combination of very simple parts which are independent of. each other for the purposes of repalrs where one part is broken.

With these general objects in' view this invention consists of the novel construction, combination and arrangement of arts all as hereinafter described in detail, illustrated in the accompanying drawing and incor orated in the appended claims. n the drawing Figure 1 isan elevation of apair of goggles equipped with the present 1m rovement. F1g. 2 is an enlarged view 0 the connections, parts of the lenses being broken away. lF1g. '3 is a section 'taken on line 3-3 of Fi 2. Fig. 4 is a perspective view of the and WlllCh supports the springs against an lar movement and carries the nose piece. in elevation of the blank out of which the Fig. 6 fittings,.straps or clamps for holdmg the ends of the connections, are formed.

Fig. 6 is a fittings.

In the several views 2 and 3 area pair of ordinary lenses equipped with the usual temples d and 5 mounted in any suitable manner. The lenses 2 and 3 are connected for a normally fixed relation to each other and also for relative angular movement by a pair of springs that are substantially identical, oneof said sprin having a coiled portion 6 and loop-ends g a the other has a coil and loop-ends 10,11

perspective view of one of the ig. 5 is a view nd 8 while which are clamped or securedto the lensesby straps or fittings such as shown separately in Fig. 6 as consisting of plates or sides 12 and 13 and a connecting yoke 14; all in one piece bent from the blank shown in Fig. 5. The loops 7, 8, 1'0 and 11 are held between the wings or plates 13 and the lenses and are fastened by rivets or screws 15 which occupy" .bores 16 and 17 in the plates 12 and 13 and similar registering 7 holes in the lenses. The spring coils are covered and supported against saggin angularly relative to adjacent edges 0% the lenses .by a band 18 which carries the nosepiece 19 secured to the band by a connecting stem 20. The band 19 may be fitted to normally contact closely with the inner edges of the lenses because when the latter are flexed the coils of the springs expand to the extent necessary for free angular movement within the required range. The jointure, while flexible, is, therefore quite firm and for all practical purposes'as firm as the usual non-flexible connections or con: necting nose-piece, or bridge. While the full size view of Fig. 1 discloses the ends of the springs for the sake of clearness, in practice only the curved sides 12 and 13 of the clips and the neat band 18 are visible, which gives a very pleasing appearance, and for commercial utility purposesthis is an important element of construction in articles to be worn on a person so conspicuou'sly as a pair of goggles. The loops 7,8, 10 and 11 are placed against the inner sides of the lenses.

I claim as my invention 1. The combination with a pair of goggle lenses, of coiled spring connections for same which connect said lenses against saggingmovement relative to each other while permitting relative angular movement of be clamped against the faces of said'le'nses,

and clips constructed and arranged to secure said loops to said lenses.

d. The combination with a pair of lenses 7. The combination with a pair of lenses.

of extensible and flexible sprlng connections secured to said lenses, a band loosely Y mountedon and incasing said connections between said lenses, ed on said band,

8. The combination with a pair of lenses,

and a nose-piece mountof a connection consisting of a spring having a coil interposed between said lenses and fiat ends lying against the faces of said lenses, means for securing said ends against movement relative to the lenses, and means for supporting said lenses in their proper relations to each other.

9. The combination with a pair of lenses, of a connection for same consisting of a spring having a coil interposed between said lenses and straight ends to overlie the adjacent ends of said lenses, means securing said ends, a nose-piece, and means supporting said nose-piece on said coil.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
